The governor of a state wanted to assess the public education system of the state. She instructed a group of researchers to create a test to assess the knowledge of every high school senior in the state. The researchers administered the tests and found that the average score was 82 points out of​100, with a standard deviation of 49 points.    b. For samples of size 200​, find the mean μx and standard deviation σx of all possible sample mean test scores.   μx=______ ​(Type an integer or a​ decimal.)   σx= ______
